Final diagnosis: Benign entrapped neuroendocrine cells (islet cells) due to chronic pancreatitis associated with IPMN.
These islet cells show atypia with hyperchromasia and arrangement in small nests, single lines or individual cells, which may mimic invasive carcinoma. Similar changes can be noted in adjacent reactive lobules.
The following picture shows a transition from residual islets (right side), to small nests (middle), and to individual cells (left).
